淄博市可吸入颗粒物时空变化特征分析

Temporal and Spatial Variation Characteristics of Inhalable Particulates in Zibo

根据"十二五"期间淄博市环境空气自动监测数据,分别对可吸入颗粒物的日均浓度、月均浓度、季均浓度进行分析。结果表明:其日均浓度、月均浓度、季均浓度呈近似"U"型分布,在时间分布上呈现冬春污染较重、夏秋较轻的规律;同时,通过对可吸入颗粒物空间分布规律分析,得出淄博市具有南部、北部地区污染轻,中部、东部和西部地区污染重的特点。

According to the monitoring data of ambient air of Zibo city during the ＂Twelfth Fiveyear＂ period, the average daily, monthly and seasonal concentrations of inhalable particulates were analyzed. The results showed that the daily, monthly and seasonal average concentrations was similar to ＂U＂ distribution, and in time distribution it had heavier pollution in winter and spring,in summer it was better; at the same time, through the analysis of the distribution of inhalable particles in space, it＇s found that the southern and northern parts of Zibo were light polluted, and the central, eastern and western regions were heavily polluted.
